2. Creating R1 devices
In the example, you add two R1 devices with system redundancy R1 to the H-CPUs. To do so,
proceed as follows:
1. Switch to the network view.
2. Drag an ET 200SP IM 155-6 PN R1 from the hardware catalog into the working window.
3. Switch to the device view of the ET 200SP IM 155-6 PN R1.
4. Drag the desired I/O modules and the server module to the respective slots of the ET
200SP IM 155-6 PN R1.
5. Repeat steps 1 to 4 for the second ET 200SP IM 155-6 PN R1.
Result: The R1 devices are created and the modules are assigned.

3. Assigning IO devices to the redundant system
To assign R1 devices to the redundant S7-1500H system, connect each interface module of
the R1 device to each H-CPU.
The left interface module of each R1 device must be connected to the left H-CPU in the
network view. The right interface module of each R1 device must be connected to the right
H-CPU in the network view.
To do so, proceed as follows:
1. Switch to the network view.
2. Drag-and-drop a line between the PROFINET interface of the left interface module of the
ET200SP-R1_1 station and the PROFINET interface X1 of the left H-CPU.
3. Drag-and-drop a line between the PROFINET interface of the right interface module of the
ET200SP-R1_1 station and the PROFINET interface X1 of the right H-CPU.
